How to import CSV using mongoimport command in MongoDB

Are you struggling to import CSV file data using mongoimport command in MongoDB ? Then this tutorial will teach you how to do that. The prerequisites to try out this example is, please ensure you had installed MongoDB server and mongoimport is available in the bin directory as shown below.

Import CSV using mongoimport

To import CSV file first you need to copy the CSV file in some location. For simplicity let’s copy the CSV file (items.csv) in “bin” directory as shown above. For example, the contents of CSV file looks like the following. There are three records in this file.

id,item_name,qty,price
1,Lenova E4430,2,98000
2,Mac Pro Desktop,1,95456
3,Microsoft LAM-00001 Surface Studio 2,1,910000

Now open the command prompt and run the following mongoimport command from “bin” directory. You should see successful message like “imported 3 documents”

> mongoimport -d sneppets -c items --type csv --file items.csv --headerline

C:\Program Files\MongoDB\Server.0\bin>mongo
MongoDB shell version v4.0.6

Enable MongoDB's free cloud-based monitoring service, which will then receive an
d display
metrics about your deployment (disk utilization, CPU, operation statistics, etc)
.

The monitoring data will be available on a MongoDB website with a unique URL acc
essible to you
and anyone you share the URL with. MongoDB may use this information to make prod
uct
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeM
onitoring()

Then switch to your database (sneppets) and run the following mongo query on the collection “items“. Please note that I have created collection called “items” and thats where we tried to import data from CSV file.

> use sneppets

switched to db sneppets

> db.items.find()

{ "_id" : ObjectId("5ca86a71d9caf05c4d9af01e"), "id" : 1, "item_name" : "Lenova
E4430", "qty" : 2, "price" : 98000 }
{ "_id" : ObjectId("5ca86a71d9caf05c4d9af01f"), "id" : 2, "item_name" : "Mac Pro
 Desktop", "qty" : 1, "price" : 95456 }
{ "_id" : ObjectId("5ca86a71d9caf05c4d9af020"), "id" : 3, "item_name" : "Microso
ft LAM-00001 Surface Studio 2", "qty" : 1, "price" : 910000 }

Now you have verified and three documents were imported. That’s all.
